BENDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 617,195, dated January 3, 1899.

Application filed October 1, 1898- Serial No. 692,423. (No model.)

To aZZ whom it may concern:

Be it known that 1, CHARLES SEYMOUR, of Defiance, in the county of Defiance and State of Ohio, have invented a new and Improved Bending-Machine, of which the following is a full, clear, and exact description.

The invention relates to bending-machines such as shown and described in the Letters Patent of the United States, No. 603,926, granted to me on May 10, 1898.

The object of the present invention is to provide a new and improved bendingmachine, more especially designed for bending wagon and carriage wheel fellies, reaches, 850., and arranged to permit of conveniently and quickly releasing the bent timber from the form.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure l is a side elevation of the improvements, with parts in section; and Fig. 2 is a perspective view of the form with the movable rim-sections withdrawn.

Theimproved bending-machine is provided with a suitably-constructed main frame or bed A, on which are mounted to swing the bending arms B B, actuated by suitable meanssuch, for instance, as shown in the patent above referred to. The bending-arms B B carry a master strap 0, on which is superposed a minor strap 0 for receiving the straight timber D to be bent into segmental form upon swinging the arms 13 B upward, as is more fully described in the patent mentioned.

On the main frame or bed A is arranged a standard E, on which is held vertically adj ustable a form F by means of a bolt G, engaging a vertical slot in the said form, as will be readily understood by reference to the drawings. The form F is provided with a segmental rim F, the ends F of which are movable inward, so as to permit of conveniently removing the bent timber D,with the minor strap, from the frame after the ends of the timber and strap are connected with each other by a shackle H. A plank I engages the timber near the ends above the upper edges of the sections F Each end section F of the form F is bolted or otherwise fastened to a slide F fitted to move on an inclined guidewayF formed on the form F, the inner end of each guideway being provided with lugs F forming journals for a transverse shaft J, carrying at its front end an arm K, under the control of the operator. On the shaft J, between the lugs F is secured a short arm L, pivotally connected with a toggle-lever N, the free end of which abuts against a projection F of the form F and rests with its free end on a lug F carried bysaidprojection. (See Fig. 1.) Each toggle-lever N is forked to receive the free end of an arm L, and said arm is preferably formed with a projecting point for engaging the toggle-lever N at the time the section F is in an outermost position-tliat is, in alinement with the rim F, as indicated in Fig. 1-- said arm L preventing a further outward movement of the section and at the same time looking the section in place, it being understood that when the section F is in an outermost position, as described, then the arm L and the corresponding toggle-lever N are in alinement with each other, and when it is desired to remove the bent timber D from the form after the operation of bending is completed and the ends of the timber are fastened together and the blank I is interposed, as described, then the operator swings the arms K inward toward each other to the position shown in Fig. 2, so that the shafts J are turned and the arms L are swung upward to permit the sections F to slide inwardout of alinement with the fixed rim F. Now it is evident that as soon as the sections F are moved inward the timber D is sufficiently released near its ends topermit of conveniently removing the timber from the form-that is, from the rim F.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-=- V 1. A bendingmachine,provided with a form having a segmental rim and inclined guide- Ways, and movable rim-seotions at the ends of the form-rim and fitted to slide in said guideways, substantially as shown and described.

2. A bending-machine,provided With a form having a segmental rim and inclined guide- Ways, movable rim-sections at the ends of the form-rim and fitted to slide in said guideways, and means, substantially as described, for moving said sections into an outermost position in alinement with the form-rim, and for locking said sections in place, as set forth.

3. Abending-machine,provided with aform having a segmental rim and inclined guide- Ways, movable rim-sections at the ends of the form and fitted to slide in said guideways, and means, substantially as described, for moving said sections into an outermost position in alinement with the form-rim, and for locking said sections in place, said means comprising a shaft journaled on the rim-sec tion, a lever for turning said shaft, an arm on said shaft, and a toggle-lever connected with said arm and adapted to abut against said form, as set forth.

4. A bending-machine,provided with a form having a segmental rim and inclined guideways, movable rim-sections at the ends of the form and fitted to slide in said guideways, and means, substantially as described, for moving said sections into an outermost position in alinement with the form-rim, and for locking said sections in place, said means comprising a shaft journaled on the rim-section, a lever for turning said shaft, an arm on said shaft, and a toggle-lever connected with said arm and adapted to abut against said form, said arm and toggle-lever being arranged to limit the outward movement of said section, substantially as shown and described.

5. A bending-machine, having a form provided with a rim over which the Work is bent, movable end portions for said rim, said end portions sliding on the form, and means for moving the end portions in and out to engage and disengage the work.
